I have had difficulty with using tags correctly and effectively.
Allow me to give an example:
When asking a question about tefilla betzibbur, which tags should be employed? The tag tefillah-betzibbur describes this question perfectly, so ideally that would be the correct tag. However, the tefilla and tzibur-community are equally relevant, although slightly higher on the hierarchical chain.
It seems absurd to employ all three tags, because tefillah-betzibbur is simply the crossover of tefilla and tzibur-community; everything tagged by it should automatically be included in its two parent tags. (For example, if one searches tefilla, something under tefillah-betzibbur should automatically be included as a subcategory.)
The problem is, both are necessary. On one hand, the more specific, the better the tag is. On the other hand, more general tags also have an advantage of being more inclusive (like when browsing, for example).
The same thing applies across the board - there are many specific standalone tags which are in reality just subcategories of more general tags. Is there any way to label subcategories to automatically be included in their parent class?
